I have found that if I try to run a vision-based LV program wihtout a valid license, the program jsut starts throwing errors on all vision funciotns, so I am looking for a way to exit the program gracefully. I thought I could use any vision funciton and act on an error output, but it seems that this doesn't work. For example, if I use IMAQmx Create, I don't get an error, even if the license is expired or not activated. But functions like Camera grab will hang the program, as they seem to have to timeout.
Not sure I'm barking up the right tree here, but any help would be appreciated.
